After the Baby Beluga post John Farrier suggested that he might just switch to teaching his kids only Klingon songs. What a great idea. I am all for encouraging your kids to learn a second language.

I could only find one reference to a real Klingon lullaby. The Doctor on Star Trek Voyager called it "Sleep Little Warrior." ( You Tube Link ) The problem is the Doctor never sings the actual song. But, don't worry I did find a great website that lists a bunch of songs in Klingon. They even have the lyrics for a few children's songs. Below is a sampling of what they offer:

Row, row, row your boat or I should say ro' ro' ylbot

toghmeH bom a counting song for the number 0 to 9

There Was an Old Lady Who Swollowed a Fly or yIH ghupbogh be' qan

I don't speak Klingon so I can't verify the accuracy of their translations, but these people seem like pretty serious scholars so I am just going to trust them.
